Use the following scenario to answer the question.
A wolf populations’ undercoat thickness follows a normal distribution. Suppose winters grow colder due to climate change accelerating because of human interference.

Over many generations, how will the distribution of undercoat thickness in this population change?
A) The distribution of undercoat thickness will no longer be normal.
B) The distribution of undercoat thickness will shift toward a thinner coat.
C) The distribution of undercoat thickness will shift toward a thicker coat.
D) The distribution of undercoat thickness will remain the same.
